Matthew 6:6
But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly.
Psalm 27:5
For in the time of trouble
He shall hide me in His pavilion;
In the secret place of His tabernacle
He shall hide me;
He shall set me high upon a rock.
